CVE-2009-4005: Buffer Overflow

Q: What is the severity of CVE-2009-4005?

CVE-2009-4005 has a moderate severity rating due to its potential for causing a buffer under-read in the Linux kernel.

Q: How do I fix CVE-2009-4005?

To fix CVE-2009-4005, you should upgrade your Linux kernel to version 2.6.32-rc7 or later to patch this vulnerability.

Q: Which versions are affected by CVE-2009-4005?

CVE-2009-4005 affects Linux kernel versions prior to 2.6.32-rc7.

Q: What type of vulnerability is CVE-2009-4005?

CVE-2009-4005 is a buffer under-read vulnerability that may be exploited through crafted HDLC packets.

Q: How can attackers exploit CVE-2009-4005?

Attackers can exploit CVE-2009-4005 by sending specially crafted HDLC packets over ISDN to trigger the buffer under-read.

Published Nov 20, 2009

Updated

The collectrxframe function in drivers/isdn/hisax/hfcusb.c in the Linux kernel before 2.6.32-rc7 allows attackers to have an unspecified impact via a crafted HDLC packet that arrives over ISDN and triggers a buffer under-read.
